我知道还有其他类似的帖子，但是大家建议直接在 PHPMyAdmin 中做到 MySQL 中（效果很好，但是我需要通过 HTML 表单导入到 PHP 到 MySQL 中。
我想要一个收集文件的 HTML 表单。然后将该文件传递给 PHP 脚本，我想知道是否可以简单地调用一个 PHP 函数，将逗号分隔的 .csv 文件转换为 MySQL 并将其添加到数据库中。
还是只能逐行解析文件并添加每条记录？

您的代码中的一切都很好，唯一的错误是您没有使用 mysql_query 将数据插入表中。 Mysql 查询未在您的脚本中运行。更正的代码如下...
<?php
if ( isset( $_FILES['userfile'] ) )
{
$csv_file = $_FILES['userfile']['tmp_name'];
if ( ! is_file( $csv_file ) )
exit('File not found.');
$sql = '';
if (($handle = fopen( $csv_file, "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
$sql = mysql_query("INSERT INTO `table` SET
`column0` = '$data[0]',
`column1` = '$data[1]',
`column2` = '$data[2]';
");
}
fclose($handle);
}
// Insert into database
//exit( $sql );
exit( "Complete!" );
}
?>

PDO 和bindParam，而不是连接一系列INSERT INTO 语句。
我们之前用过这个，效果很好。只需注意您的文件和目录权限。 csv_upload_mysql_conf.inc 只是数据库链接。这将一次解析多个文件，并将它们放在一个名为 import 的表中。相应地更新。
<?php
/* The conf file */
include_once "csv_upload_mysql_conf.inc";
$php_self = $_SERVER['PHP_SELF'];
$file_open = 0;
$file_exts = array
( 'csv');

我还没有完全测试过这个，但我看不出它有什么不工作的原因。
<?php
if ( isset( $_FILES['userfile'] ) )
{
$csv_file = $_FILES['userfile']['tmp_name'];
if ( ! is_file( $csv_file ) )
exit('File not found.');
$sql = '';
if (($handle = fopen( $csv_file, "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
$sql .= "INSERT INTO `table` SET
`column0` = '$data[0]',
`column1` = '$data[1]',
`column2` = '$data[2]';
";
}
fclose($handle);
}
// Insert into database
//exit( $sql );
exit( "Complete!" );
}
?>

当然，您需要先验证数据。
